Other Parts Discussed in Thread: ISOS141-SEP,
Hello,
I am trying to use the ISOS141-SEP in conjunction with the SN65C1168-SEP to create an RS-422 rated UART transceiver system. The main reason these parts were chosen was due to the existing App Brief and the need to shift the voltage down from 5V to 3v3 so that our Microcontroller could interface with it.
However, I need some assistance to understand what to do with the unused pins, wither to ground them or tie them up with a 10k.
Our Schematic
The reference circuit:
App brief location:
Space-Grade, 30-krad, Isolated RS-422 Serial Transceiver Circuit (ti.com)
Please do let me know what yo do with the unterminated connections to make sure that the devices will work as intended together. Specifically:
